OVERFLOW APPARATUS FOR CESSPOOLS.

SPECIFICATION forming part of Letters Patent No. 237,796, dated February15, 1881.

Application filed December 9, 18H0. (No model.)

To all lwhom it may concern.-

Be it known that I, GEORGE W. ALEXAN- DER, of the city of Baltimore andState of Maryland, have invented certain Improvements in OveriowApparatus for Gesspools, &c., of which the following is a specification;and I do hereby declare thatin the same is contained a full, clear, andexact description of my said invention, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

This invention relates to means for deodorizin g and disinfecting theoverflow-water from cesspools, in order that the same may be dischargedto a sewer.

In carrying out my invention I provide the cesspool with anovertlow-pipe having preferably a strainer at the inner end thereof,which extends to the sewer to which the over` now-water is to bedischarged, and located in the said overoW-pipe is a deodorizing anddisinfecting trap of peculiar construction, which separates from theoverflow-water the ottensive and injurious matter contained therein.

In the further description of my said invention which follows referenceis made to the accompanyin g drawings, forming a part hereof, and inwhich- Figure I is a vertical section of the invention, and Fig. II aplan ofthe same.

Similar letters of reference indicate similar parts in both the views.

A is the cesspool or sink into which fecal and other waste matter isintroduced.

B is the overtlow-pipe, having a strainer at its inner end to preventthe entrance to the pipe of the larger solid portions ofthe contents ofthe sink.

O is a well, situate, like the sink, in the ground, to which the outerend of the overilowpipe is connected. The well O has a removable cover,a, accessible from the surface ofthe ground; and a removable basket, b,containing charcoal or other` suitable disinfecting and deodorizingmaterial, is placed in the well in such position as to receive theoverIiow-water as it enters the same. The overliow-water, afterpercolating through the charcoal, is discharged through the pipe D tothe sewer E. The inner end of the discharge-pipe D is bent downward, asshown, so as to be below the main part of the pipe, and thereby form atrap to prevent noxious gases passing from the sewer when the water inthe well is below the upper inner surface of the pipe D, as shown in thedrawings.

The basket bis provided with devicessuch as eyebolts or handles-wherebythe same may be lifted out when the disinfecti ng and deodorizingmaterial is changed.

The operation of the invention is as follows: When the water in thecesspool or pit rises to a point on a line with the horizontal portionof the pipe B it overflows to the well (l, and is received by the basketb therein, which holds the offensive matter contained in the water andallows the cleansed liquid to pass to the bottom ot' the well. Upon thewater rising in the well to the horizontal portion ot' the dischargepipeD it is carried to the sewerE. Theinner end of the discharge pipe Dbeing turned downward in the well, as shown, a trap is 'formed whichprevents gases tlowing from the sewer when no discharge ot' water istaking place, as will be readily understood.

This invention obviates the difficulty of ridding cesspools of waterintroduced thereto from Water-closets without contaminating sewers, andat the same time the frequent cleanin g out of the cesspool is renderedunnecessary, which is a great saving ofexpense.

I claim as my inventionl. In combination with a cesspool, anoverflow-pipe, a well connected to the said cesspool by the said pipe, abody of deodorizing and disinfecting material located in the said well,and a discharge-pipe leading from the said well to a sewer,substantially as herein specified.

2. In combination with a cesspool, an overlow-pipe leading from thesame, a well situated in such position as to receive the overoW-water, aremovable basket for charcoal or other like disinfecting and deodorizingmaterial, and a discharge-pipe leading from the said well to a sewer,having its inner end in the well turned downward to form a trap forgases, substantially as herein specified.

GEORGE W. ALEXANDER.
